From "From the Creators:"
This is the first in a series of creature packs we are publishing on a weekly basis so players and game masters alike can bring new material to the table every session. It is our hope that Creature Weekly will have something for everyone.
Not everyone runs fantasy games, however. Rather than provide mixed–genre creatures that only work in some settings we have set out to provide you with the tools you need to quickly and easily adapt each creature for your own campaign, whether it is set in the wilds of a lost elven kingdom, in the concrete maze of a modern urban sprawl or in the cold depths of space. Check the “Variant Rules” box with each entry to help adjust game mechanics.
The “Alternate Genres” section is there to provide suggestions for adjusting the concept of each creature for non–fantasy settings.
